Answer: By studying the fossil record we can tell how long life has existed on Earth, and how different plants and animals are related to each other. Often we can work out how and where they lived, and use this information to find out about ancient environments. Fossils can tell us a lot about the past.
Producers get the energy they need from the sun. Consumers get their energy from the plants and animals that they eat. Decomposers get energy from eating dead plants and animals.<span />
1. tetrapods are ( four-limbed animals ) . examples of tetrapods include (extanct and extinct amphibians , reptiles , and mammals )
2. Tetrapods first appear in the fossil record ( 367.5 ) million years ago .
3. Charles Darwin predicted that tetrapods evolved from ( a finned organism that lived in the water) . What observation leads do that hypothesis?( they have “fleshy fins” and “lobe fins”) .
5. Fish use ( gills ) to breathe underwater .
The answer is A. Morphology/anatomy is considered more
relevant than behavior or general appearance in the classification of organisms. It
is due to these anatomical features that animals such as bats are classified differently
from birds (with bats classified as mammals even though they fly like birds) due to differences in anatomical features
like milk-producing glands and brain structure.
